TPS65987D: please suggest the PD to NVDC-1 charger OTG and embedded controller I2Cs connection

Sir,.

please suggest the TPS65987D to BQ25713 OTG function DSP I2Cs connection .

had read specification which be  I2C1 master or Slave, I2C Slave ,I2C3 master

ex. DSP -> I2C1 -> TPS65987D, 

     TPS65987D   ---->< ----I2C3 -><---BQ25713, 

     DSP went TPS65987D GPIO to PD characteristic 

Cann`t find correct reference , thanks
